ABSTRACT:
A versatile operating mechanism for a two-point latch or lock includes a "front" module having a flush-mountable handle and housing assembly that can be connected by simple fasteners to a "rear" module having a mounting bracket that movably supports linkage including an operating arm A pair of latch assemblies are connected to and operated by the mounting-bracket-mounted linkage. In preferred practice, rotary latch assemblies are used that each employs a single rotary jaw that is releasably retained in its latched position by a rotary pawl, with the latch having a pair of spaced housing side plates that sandwich the rotary jaw and the rotary pawl, with the side plates defining aligned first and second U-shaped notches that cooperate with a third U-shaped notch formed in the rotary jaw for concurrently receiving and latchingly retaining within the confines of the first, second and third U-shaped notches a suitably configured strike formation, with housing side plate portions that define a selected one of the first and second U-shaped notches being rigidified and strengthened by the close proximity presence of a flange 1) that is formed integrally with side plate portions that define the selected notch and 2) that extends transversely to bridge between the housing side plates at a location near the first and second U-shaped notches. The operating mechanism may be "locked" by positioning a movable locking member to extend into a path of movement of the operating arm to selectively permit and prevent movement of the operating arm along a path of movement.
